The STEM used to be an NIH Research Resource and as such was available to outside users with appropriate projects free of charge.
We have lost this support, but continue to operate half-time as a User Facility on a Fee-For-Service basis.

Our web page (link given above) has essentially all the useful information about the facility and its use.

We will try to use this page for transient information, such as announcements and "news".

A NEW POSTING

The microscope is now running with our new computer system. STEM Users who have been using the STEM PCMass programs for analyses and viewing, should be using the most recent version of PCMass29. It reflects the new data acquisition system, is much more user-friendly, and has more tutorials. The new, complete, PCMass29 program is now on our ftp site.
